3 Installation
If for any reason you can assume that the unit it not safe
to operate, shut it down and secure it so that it cannot be
inadvertently turned on again.
You can assume that the unit is not safe to operate when
•
it has sustained visible damage
•
it no longer functions
•
it has been stored for a longer period under unfavor-
able conditions
•
it has been subjected to severe transport stress
•
when the screws of the plug-in boards are loose or
missing.
3.1 Mains power connection
You can connect the TPG 300 without voltage adaptation to any
conventional supply system (
→
section 5.1).
The power connector may only be plugged into a socket
with a protective ground. Only three-pin mains cables with
a correctly connected protective ground may be used.
This protection must not be nullified by an extension cable
without ground conductor.
To assure continuous grounding protection, connect the
mains power cable before connecting any other cables. In
the same way, disconnect all other cables before discon-
necting the mains power cable.
If the unit is installed in a rack, the mains voltage should
be supplied by and turned on via a central distributor.
